<H2><A NAME="8_22">8.22  Adding static lines to the plot</A></H2>
<P> In addition to the bands you can also add static lines to the graph.
 An example of that is actually shown in figure 11 above. You create a
 line as an instance of <A href="../ref/PlotLine.html#_C_PLOTLINE">
 class PlotLine</A> . So for example the lines<DIV class="phpscript"><CODE>
<FONT color="#000000"> <FONT color="#0000BB">&nbsp;$sline&nbsp;</FONT><FONT color="#007700">
=&nbsp;new&nbsp;</FONT><FONT color="#0000BB">PlotLine</FONT><FONT color="#007700">
